It is an opinion often ventured that Heidegger, having opened very briefly – in Being and Time – the question of birth, fails to properly engage the matter. It is said that, despite the thinking of historicity initiated there, and the occasional reference in later writings, the question of the natal is not properly addressed in his work. Instead, we are told, it is Hannah Arendt who picks up this neglected thread, turning it into a cornerstone of her thinking. This paper seeks to show that this story is inaccurate: that the development of a conception of ‘Anfang’ in the texts of the late 1930’s can be seen to address in a decisive manner the question of what will be called ‘natality.’ Aspects of the texts from this period, and in particular of the volume Über den Anfang (GA 70) can be read so as to reveal a rich and complex response to this problem, one that reverses many presuppositions regarding Heidegger’s work at this time, and more than filling this apparent lacuna.

Hawthorne's years in England, the least studied phase of his career, are especially significant for the challenge that English materialism posed to his New England austerity and his romancer's idealism. Beyond recording his complex response to English life and character, his “English Notebooks” and “Our Old Home” show how England permanently inflected his character and sense of experience.

<p style="text-align: justify;">La présence de mycorhizes à vésicules et arbuscules (VA) est très répandue dans les vignobles. Le symbiote fongique peut influencer positivement l'absorption de phosphate et par conséquence la croissance de la plante. Les données expérimentales relevées jusqu'à présent permettent d'envisager l'application artificielle des mycorhizes VA dans quelques domaines de la viticulture.</p><p style="text-align: justify;">+++</p><p style="text-align: justify;">Vesicular-arbuscular (VA) mycorrhizae are widespread in vineyards. Their structures allow an improved phosphate nutrition and consequently an enhanced growth of the vine, specially in P-deficient soils. Experimental results obtained up to now show the interest in the use of artificially introduced VA mycorrhizae in some areas of viticultural practice.</p>

Abstract The dentine-pulp complex response in deep caries is histological characterized by tertiary formation and mild chronic pulp inflammation. The quiescent primary odontoblasts are reactivated, laying down reactionary tertiary dentine. In more severe carious damage the primary odontoblasts die and reparative tertiary dentine is secreted by odontoblast-like cells, which are differentiated in adult teeth mainly from dental pulp stem cells DPSC. Though associated with reversible pulpitis DPSC still preserve in deep caries the capability of migration, proliferation and differentiation. Some common mechanisms of molecular signals involved in tertiary dentine formation might also explain the balance between inflammation and regeneration of dentine-pulp complex.
